Study Notes
Vocabulary Words Related to Photosynthesis
- Autotroph: Organisms that produce their own food by capturing energy from sunlight or chemicals using inorganic compounds; referred to as producers.
- Heterotroph: Organisms that derive energy by consuming food; known as consumers.
- Adenosine Triphosphate (ATP): Primary chemical used by living organisms to store and release energy, essential for cellular functions.
Processes and Structures in Photosynthesis
- Photosynthesis: A crucial biological process where plants and some organisms convert water and carbon dioxide into oxygen and carbohydrates (like sugars and starches) using light energy.
- Pigment: Molecules that absorb light, playing a significant role in photosynthesis.
- Chlorophyll: The main pigment in plants and photosynthetic organisms, vital for capturing light energy.
Components of Chloroplasts
- Thylakoid: Membrane structures within chloroplasts that contain chlorophyll and are integral to the light-dependent reactions of photosynthesis.
- Photosystem: Functional units in chloroplasts that collect light energy for photosynthesis.
- Stroma: The fluid-filled space surrounding thylakoids in chloroplasts, where the Calvin Cycle occurs.
Energy Carriers and Enzymatic Functions
- NADP+: A carrier molecule that transfers high-energy electrons from chlorophyll to other molecules, playing a key role in the electron transport chain.
- ATP Synthase: A large protein that synthesizes ATP by using energy from H+ ions, illustrating the connection between ionic movement and energy production.
The Calvin Cycle
- Calvin Cycle: A series of biochemical reactions in photosynthesis that utilize ATP and NADPH to synthesize high-energy compounds like sugars, showcasing the transformation of solar energy into chemical energy.
